I purposed her and she told me don't show me your face again, was that clear rejection?

I like a girl. She comes to the grounds to walk her dog where I met her. She used to point to talk to me and was shy around me but due to my shy nature I could not talk to her but somehow I manage to talk to her. Her family also knows about me. She always used to ask me why I come to talk to her but I avoid answering because I don't know about her properly. Sometimes I made her angry but she got convinced. We haven't been talking for a week and I decided to talk to her. So I went to talk with her and at that time she was angry with me but I told her that I like her and she replied to me "don't show me your face again", what was that mean?

I purposed her and she told me don't show me your face again, was that clear rejection?
